3 SHEETS-SHEET 3- UNITED STATES FATE JOHN FARLEY,-OF IIISCARD, ENGILAND- To all whom it may concern:

Be it known thatl, JOHN FARHEY, a subject of the King of-Great Britain, and a resident of ,Liscard, Cheshire, England,

new and useful Im-' Air Cooling, Filterhave invented certain provements Relating to ing, Purifying, Aromatizing, or the like Apparatus, of which the following is a specification.

This invention relates to apparatus for use in filtering, purifying, or otherwise treating the air of rooms or the like, suchas sick rooms, railway dining cars, picture halls, "or the like. The function of the usual ventilating fanis in many cases merely to churn the air around, and the object of the present invention is to combine with the fan a means for purifying or treating the air current set up by the fan.

According to this-invention an air fan is provlded, driven in any suitable manner,

say by an electricmotor, and mounted in front of the fan, in such manner that the take place panying drawings, in whichair from the fan is driven therethrough, is a grid or the like device made of a series of tubes orducts, the'sides of which nearest the fan are open, or the tubes may be perforated. Means are provided, say a small centrifugal pump driven from the fan motor, for causing a circulation of water or other liquid to through the tubes of the grid. The liquid may be merely water for the purpose of cooling the airand entrapping dust and fiber which is then carried away in the water flow, or water impregnated with disinfectants or perfume.

The invention is illustrated in the accom- Figure 1. is a side view of one form of the apparatus, and Fig. 2. a view looked at from the right of Fig. 1. Fig. 2 is a cross section through one tube of the grid showing a wire for preventing spraying of the liquid. Fig. 3 is a side view analogous to Fig. 1. of

a modified arrangement of theapparatus in which the wellforms the base of the vfan and Fig 4. is a plan view of Fig. 3.

In the form of the apparatus shown in Figs. 1. and 2, an electrically driven air circulating fan 1 is provided carried from a suitable bracket orstandard 2. the spindle 3 of the fan and the motor 4 being either geared or coupled to the spindle of a centrifugal or other circulating pump 5 or such pump. may, as shown, be mounted direct on Specifination of Letters Patent.-

the rear of the'fan spindle. The pump 5 is adapted to draw a supply of water, or water permeated with disinfectant or the like, from a storage tank or Well 6, which after being passed through aseries of tubes 7 disposed in front of the fan 1 is returned to the well 6 by a gravity flow. A suitable d- I livery pipe 8 is provided, coupled at 9 to the pump, for v leading the circulating fluid to the pipes, a smaller connection 10 being provided for returning the circulating fluid to the well 6, the suction pipe 11 of the pump 5 being carried below the level of liquid in the well. The tubes 7 are' arranged in an upright series connected at the top and bottom to supply and return flow trunk pipes 12, 13. The upright tubes'are open at 7 on' their sides nearest the fan, and the plane of the tube grid mayv be inclined slightly from the vertical, as shown in Fig.

.1. The inlet: trunk pipe 12 of the grid has a series of small perforations 12 each perforation being at about the center of the bore 1 pipes of the uprighttubes 7 of the grid, so that a series of water jets or sprays are directed pipe 13 when the liquid circulating pump 5 is .in operation. By inclining the grid from the vertical, thesejets cascade down the rear walls of the tubes 7 the air-being driven by the fan against. the water jets andall dust, fiber or the like being abstracted from the air by being caught in the jets on the wet walls of the tubes, and returned to the well. If desired, a filter may be fitted in the well 6, so that such foreign matter may be retained therein and not again circulated through the tubes. Detachable plugs 14: may

means of a capillary action, absolutely preventing any possibility of spraying of liquid past the tubular grid.

- In-the modification shown in Figs. 3 and 4, the wheel 6 isarranged as a pedestal for the standard 2 of the fan, the tube grid 7 being supported from the flow and return 8, 10 of the pump which are both branched from the well 6. The suctionvpipe' the down the upright tubesto the return trunk 11 to the pump 5 is carried down into the Well, the delivery pipe 8 from the pump being also carried down into the Well and through it, as indicated by the dotted lines 8, and thence up the side tube 8 to the top trunk pipe 12, being then delivered through .the open-side tubes 7 as previously described, and passing by Way of the lower trunk pipe 13, returned by the pipe'lO to the"vvell. Such a construction provides a very simple and compact arrangement of the apparatus. A stay 15 may be fitted to support the top of the tube grid from the casin of themotor 4, and the floor 6 of the Wel may be cupped, as shown in Fig, 3., and a pipe 6 provided for draining the -Wll. In

C order to enable the liquid circulation to be and delivery pipes 8, 11 of the supply well. ]By forming the tubes 7 open only on the side nearest the fan 1, the descending Water jets are prevented from being sprayed or blown into the room, the rear wall of-the' tube avoiding this and enabling the Water to be returned 'to the well, although permitting intimate contact of the air current with the circulating water.

I claim 1. Apparatus for cooling, purifying aro matizing, or otherwise treating the 'air of rooms or the like, comprisiiig,in combination, an air fan, a tubular grid in front of the fan having one of its sides open, a storage tank for liquid, and a centrifugal pump onthe --fan spindle adapted to circulate liquid from the tank through the tubes of the grid.

2. Apparatus for cooling, matizing, or otherwise treatlng the a1r of rooms or the like, eomprising, in combination, an air. fan, a tubular grid in front of the fan having one of its sides open, the tubes.being open on-their sides nearest the fan, a series of wires mounted in the'tubes, a storage tank for liquid, and a pump adapted to circulate the liquid from the storage tank through the tubes of the grid.

3. The combination with a fan, a device for treating air comprising a fluid tank, a tubular grid positioned in front of the fan, said grid having one of its side faces open,

a supply'pipe connecting the fluid tank and- I 65 forcing fluid through the supply pipe, grid and re-" grid, a return pipe for connecting the grid with the fluid tank, and means for turn pipe.

4. In combination with a fan, a device Ior;

treating air comprising a'fluid tank, a tubular grid having one of its side faces open supported in frontof the fan, said grid being supported at an angle with relation to the fan, means for connecting the grid with the fluid; tank, and means for forcing fluid from the fluid tank through the grid.-
